IMPROVEMENT IN BINDING ATTACHMENTS 'I'O HARVES'I'ERS.

Specification forming part of Letters Patent No. 22,074, dated November16, 1858.

the following is a full, clear, and exact de-- scription of the same,reference being had to the accompanying drawings, forming a part of thisspecification, in which- Figure 1 is a longitudinal section at a: 0:,

. Fig. 3. Fig. 2 is a transverse section at y 3 Fig. 3. Fig. 3 is a topview, the platform and a portion of the flooring being removed. Fig. 4is a perspective View of the front part of the machine, the frontfioorin g being removed.

The accompanying drawings represent a machine embodying my improvement,and adapted for attachment to a self-raking harvestersuch, for instance,as that patented to J earum Atkins, December 21, 1852.

Thisinvention consists in an arrangement of means, substantially ashereinafter described, for the automatic binding of grain with a portionof its own straw.

A is a bed or frame, supported on customary ground-wheels B B G, ofwhich the wheel B is the driving-wheel. Resting on the bed A is aninclosing-box, D, whose top is floored, E E, at each end. The intervalbetween the floor E and the floor E is occupied by a platform, F.

The platform F has a hinged attachment to a bar, G, which bar is thefirst of a connected series of compound levers, G H I J, having theirfulcra at g h i j, respectively.

The rear end of the last lever, J, affords journal-bearing to a shaft,K, near its right end, the left end of the shaft K journaling in astationary bracket, L.

The right or yielding end of the shaft K has a spur-wheel, M, which, inits normal or upper position, is unaffected by the advance of themachinealong the ground; but which, when the platform. F is depressed bya charge of grain, sinks into gear with a spur-wheel, N, at the back ofthe driving-wheel B, so as to be rotated by the latter.

0 is a spring, which restores the levers G H I J, spur-wheel M, andplatform F to their upper or normal position the instant that theplatform is relieved of its load.

Near the ,mid-length of the shaft K is a segmental bevel-wheel, P, whichgears to a smaller bevel-wheel, Q, on one end of a shaft, R, whose otherend has a similar bevel-wheel,

S, which gears to an inverted crown-wheel,

T, on an upright shaft, U, which shaft is surmounted by a fixed jaw, V,and a hinged jaw, W.

X is a fixed horizontal bracket, having a round hole, through which theshaft U rises. This hole, being eccentric with the shaft U, causes theloose jaw to close against the other by the rotation of the said shaft.The shaft U, jaws V, WV, and bracket X, I call, collect ively, thepliers I I.

The left end of the shaft K has a spurwheel, Y, which gears to a similarwheel, Z, on a horizontal shaft, z, immediately over the shaft K. Theshaft 2 has, near its mid-length, a cam, a, whose rotation pushesforward, at the proper moment, a yoke, b, armed with a rod, 0. d areeyes which serve to guide the rod 0. c is a spring, which retracts therod when released by the cam. f is a segmental spur-wheel, mounted onthe right end of the shaft z, for purposes hereafter explained.

The spur-\vheelY has around half its circumference a set of bevel-cogs,g, which gear "to a pinion, it, on a shaft, 1, which shaft has twocranks, m a, connected, by pitmen, 0 p, to levers q r, to whose upperends are hinged, respectively, two rods, 8 t, whose free ends rest inguides to e, and are notched, as shown. These rods 1 term, respectively,the looper s and the tucker-in t.

A standard, 1, which rises vertically from the floor E, has projectinghorizontally from it journal-boxes 2 4, for a sliding and revolving stemor post, 3 3, whose lower enlarged portion, 3, is grooved to receive alozenge-shaped lug, 6, projecting from a fixed semicircular yoke, 7,which incloses and guides the stem at this part. The lower part, 3, ofthe stem, called by me the barrel, has a rack, 8, which gears to thesegmental spur- Wheel f, before mentioned.

9 is a collar on the stem 3. 10 is a spiral spring, which, extendingfrom the box 4 to the collar 9, serves to restore and hold the stem andits appendages to their upper or normal position when released by thewheel f.

A bracket, 11,journaled to the upper part of the stem B, is providedwith two journalboxes, 12, which support a horizontal shaft,

' 13, which is mounted at each end with a bevel cog-wheel, gearing withcorresponding wheels attached, respectively, to the stem 3 and to avertical shaft, 14, which is also journaled in boxes supported by thebracket 11.

The stem 3 3, bracket 11, and their accessories I style, collectively,the crane, I I I.

15 is an ellipticalv spring, attached at its upper side to the shaft 14,and connected at its, lower side with two curved arms, 16 16, which havenotched extremities, called by me the talons. Each talon is composed ofa fixed spur, 17 17, and an adjustable spur, 18 18.

The platform F has an H-formed perforation, 19, to admit the passagethrough it of these talons, and of the band or wisp of straw, ashereafter set forth.

20 is a heel projecting from the bracket 11, and which,by striking thestandard 1, arrests, at the proper instant, the forward swing of thebracket, so as to cause the remaining rotation of the stem to beexpended in rotating the talons, as hereafter explained.

This machine may be so modified as to be applicable to otherdescriptions of harvesters.

The operation is as follows: The front part (marked with an asterisk inFig. 4) being suitably attached in the rear of an Atkins or otherself-raker, in such position that the gavel will be deposited on theplatform transversely to the machine, such deposition ot the gavelbrings, as before explained, the operative parts into connection withthe drivingwheel, the result of which is, that the crane, actuatedthrough its rack 8, and confined to a specific path by the lug 6 in thegroove 5, descends in a right-hand spiral direction until its talons areinserted in the gavel so as to fill their crotches with straw. Then, thegyration of the crane-bracket 11 being arrested by the impingement ofthe heel 20 against the standard 1, the motion of the stem 3 3 iscommunicated, through the shafts 13 and 14, to the arms 16 16, so as toplace the latter astride of and pressing down upon the gavel, carryingwith them a wisp of straw through the aperture 19 in the platform, and

so that the ends of the wisp are introduced bundle, and also to twistthe ends of the wisp together. I

The rod 0 then advances in front of the twisted wisp, so that theforward motion of the looper S forms a loop, which is then taken by thetucker-in t, and the pliers V W, at this instant releasing their hold ofthe ends of the band, the latter are tucked'beneath the band in asimilar manner to that performed by hand. Meantime the ascent of thecrane has drawn the arms 16 16 up through the platform F, and the craneswinging back, this action causes the now bound sheaf to be swept offthe platform by the arms 16 16, and the machine is then ready foranother gavel.

What I claim as my invention, and desire to secure by Letters Patent,is-- 1. The arrangement of gravitating-platform F 19 and series ofleversG H I J, with their accessories, in the described connection witha drive-wheel, for the automatic starting of the binding mechanism bythe weight of the sheaf or gavel, substantially as set forth.

2. In this connection, the talons 16 17 18 16 17 18, constructed andoperating substa-ntially as set forth.

3. In combination with the talons or their equivalent, the crane I I Iand its accessories, having the described compound movement,substantially as and for the purpose set forth.

4. In the described combination with the talons or their equivalent, thepliers I I, constructed and operating substantially as set forth.

5. The rod 0, looper s, and tucker-in t, constructed, operated, andoperating together substantially as set forth.
